By Roberto PedoneWINDERMERE, Florida ( Stockpickr) -- Copper is printing fresh four-month highs today, off reports out of China that its manufacturing economy saw a moderate expansion in August after slowing down for several months. China's official purchasing managers index rose to 51.7 in August from 51.2 in July, exceeding forecasts, according to a government-baked report. Three-month delivery of copper surged around 2% to $7,585 a metric ton off the news, the highest level it has seen since April 27. What's interesting about the recent uptrend in copper is that the bulls have been pushing it up while the overall economic numbers have been coming in weaker than expected. This shows that copper has been in a counter-trend rally with the metal also advancing, while bonds are going up and stocks trending down. This is not normally how copper will trade, since this precious metal is often thought of as a leading economic indicator. So either both equity investors and bond investors have it wrong, or copper investors have it wrong. Time will soon tell if copper players are on the right side of the trade or if their bullishness is misguided. It's very possible that the copper-players are piling into the commodity ahead of better economic times down the road. The message from the market could be that the bad economic news is mostly priced in, since copper has been trending strong in the last couple of months. If this is the case, investors are going to want to start searching for some top copper stocks to play this possible new uptrend. Here 's a look at a number of stocks that offer investors exposure to copper.
